A shrine maiden chosen as a human sacrifice to break the barrier between the demon world and the human world. Though pure of heart, she becomes ensnared in a cruel ritual. Her nipples are intensely aroused by pump suction, tortured with chopsticks until she can no longer endure the pleasure. Sacred hemp ropes are pressed between her legs as she is whipped and taunted, sinking deeper into the sweet ecstasy of masochism. The girl's innocent soul gradually warps under the brutality of the ritual, transforming into a new form. This process captures both her sorrow and pleasure in vivid detail.
